IMFPMPHost interface

Enables a media source in the application process to create objects in the protected media path (PMP) process.

Members

The IMFPMPHost interface inherits from the IUnknown interface. IMFPMPHost also has these types of members:

Methods

The IMFPMPHost interface has these methods.

MethodDescription
CreateObjectByCLSID

Creates an object in the PMP process, from a CLSID.

LockProcess

Blocks the PMP process from ending.

RemoteCreateObjectByCLSID

Remotable version of CreateObjectByCLSID. (Not used by applications.)

UnlockProcess

Decrements the lock count on the PMP process.

 

Remarks

This interface is used when a media source resides in the application process but the Media Session resides in a PMP process. The media source can use this interface to create objects in the PMP process. For example, to play DRM-protected content, the media source typically must create an input trust authority (ITA) in the PMP process.

To use this interface, the media source implements the IMFPMPClient interface. The PMP Media Session calls IMFPMPClient::SetPMPHost on the media source, passing in a pointer to the IMFPMPHost interface.

You can also get a pointer to this interface by calling IMFGetService::GetService on the PMP Media Session, using the service identifier MF_PMP_SERVICE.
